Synopsis

Description

This administrative configuration program allows uDAPL service providers to add and remove
themselves to the dat.conf file.

You can add or remove interface adapters that a service provider supports
from a system after its installation. You can use datadm to update
the dat.conf file to reflect the current state of the system. A
new set of interface adapters for all the service providers currently installed is
regenerated.

Options

The following options are supported:

-aservice_provider.conf

Enumerate each device entry in the service_provider.conf(4) file into a list of interface adapters, that is, interfaces to external network that are available to uDAPL consumers.

Examples

Assume that SUNW has a service provider library that supports the device
hermon. It has a service_provider.conf(4) file installed in the directory /usr/share/dat/SUNWudaplt.conf with
a single entry as follows:

hermon is an Infiniband Host Channel Adapter with two ports. Both IB
ports exist in a single IB partition, 0x8001. If an IB partition
is created and plumbed to each port (with the names p8001.ibd0 and
p8001.ibd1), there will be two IB partition instances. See dladm(1M) for more information
on creating IB partition data links.

Example 2 Updating the dat.conf to Reflect the Current State of the System

A new IB partition, 0x8002, is added to the above example covering
port 1 of the Host Channel Adapter. If a new IB partition
is created on the port 1/partition 0x8002 with the partition link name
specified as p8002.ibd0, there will be a third IB partition instance: p8002.ibd0.
